INSOLE-MACHINE.

To all whom it may concern.'

Be it known that I, ANDREW EPPLER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Insole-Machines; and I do hereby declare the following to be a full, clear,`and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. j

This invention relates to improvements in insole machines.

The object of the invention is to improve the construction and operation of insole niachines generally, and particularly toproduce an improved machine for use in making insoles of the type in which two flaps are severed from the insole by oppositely disposed cuts and are bent upward against each other to form a compound lip.

To the above ends the invention consists in the improved insole machine hereinafter described and claimed.

In the drawings Figure 1 is a front elevation of a machine embodying the invention; Fig. 2 is a side elevation; Fig. 3 is a plan View; Fig. 4 is a sectional lan View taken on the line .fnx, Fig. 1; ig. 5 is a vertical section on line g/-y Fig. 4, ofthe -edge gage adjusting means; Figs. 6 and 7 are details in plan of the same part; Fig. 8 is a vertical section of the knife carrier; Fig. 9 is a rear view of the same; Fig. 10 is an enlarged perspective showing the manner in which the knives and hammer operate upon the work, and Fig. 11 is a detail view showing the feeding device engaging an insole.

The illustrated embodiment of the. invention 'comprises a rotating work support, a channeling knife and a slitting knife mounted on an oscillating carrier, a four-motion feedin device for feeding the insole against the knives, an adjustable edge gage for re ulating the distance of the lip from the e ge of the insole, a vibrating halnmer for setting in .an upturned position the flaps c ut by the knives, and mechanism for actuating these parts. j

The'work support l comprises a fiat circular table fixed to a stem 2 which rotates in a. sleeve 3 forming a part of the frame of the machine so that the work may be fed easily over the work support. ln order to Speciication of Letters Patent.

accommodate itself to various thicknesses of work, the work support is arranged to yield vertically, and is supported by a spring 4 pressing upward against the stem 2. The upward movement of the work support is limited by a stem 5 carrying adjustable nuts 6 which bear against the under side of a block 7 through which the stem 5 passes. The block 7 is arranged to slide in the sleeve 3 and has a lug 8 extending outward through a vertical slot in the sleeve and connected with a toggle comprising a link 9 and a bell crank lever 10. When the toggle is in the position shown in Fig. 1', the work support is maintained in its raised position and pressed upward firmly against the work by means of the spring 4.

In order to insert an insole in the machine the work support may be lowered by means of 4a suitable treadle connected at 11 with the toggle lever 10 and arranged to break the toggle and draw the b1ock'7 and the other parts of the work support downward. When the treadle is released a spring 12 returns the parts 4to the position of Fig. 1. The movement of the toggle is limited by a pin 13 fixed to the frame. i Owing to the above-described arrangement the work support may be easily lowered by the treadle without the necessity of compressing the comparatively strong spring 4.

The work is fed by a feeding device 14. As shown in Fig. 11, the feeding device has points 15 to engage the work, and these are arranged to act upon the surface of the insole upon both sides of the uncut portion between the cuts produced by the channeling knife and the slitting knife, so that the work is fed positively, but the indentations produced by the feed points do not weaken the between-substance. The feeding device is secured to a carrier 16, the upper slotted end of which is guided by a stub 17 pivoted to the frame of the machine. The lateral movements in the direction of feed are imparted to the vcarrier 16 by a slide block 1S engaging the slotted central portion of the carrier and pivotally mounted on a. stub 19 fixed eccentrically,'as shown in Fig. 1, to the forward end of the drive shaft 20 by which the machine is actuated. The drive shaft is journaled in the frame of the machine and carries a pulley 21 by which it is rotated. The longitudinal movements which cause the feed points to engage and disengage the work are imparted to the carrier 16 by a cam roll 22 engaging a cam ath 23 in a cam 24 fixed to the forward en of the shaft 20.

By the operation of means above described the feeding device first engages the work, movesfroi'n right to left (Fig. 1) then rises to disengage the work and returns from left to right to a position to again engage and feed the'work.

The feeding device 14 is secured to the carrier 16 by screws 25 engaging slots in the feeding device, and this construction permits vertical adjustlnent of the feeding device to regulate the pressure with which it engages the work.

The channelin cutting edge 27 or severing a flap from the upper surface of the insole, and a plow 28' for turning this flap up into a position substantially perpendicular to the surface of the insole. The slitting knife 29 has an inclined cutting edge 30 for cutting a slit in the margin of the insole near its upper surface, and the shank of the slitting knife acts to turn this flap up against the channel flap, as shown in Fig. 10. The lmives are both adjustably fixed to a knife carrier 31, which, as shown in Figs. 8 and 9, is arranged to slide vertically on an arm 32 fixed to a rock shaft 33, the shaft being journaled in the frameof the machine'and provided with a collar 34 to prevent longitudinal movement. The arrangement of the two knives on one carrier simplifies `the construction of the machine, and insures the proper relative position of the knives. The arm 32 'and the knife carrier and knives are vibrated in the line of feed b means of a cam roll 35 pivoted on a stu 36 fixed to the arm and eugaging a cam path 37 in the Side of the cam 24. During the feeding of the work the cam imparts two rapid vibrations to the knives so that they cut by a chopping action at the time when the work is engaged and held by the feeding device. In order t`0 press the knives yieldingly against the upper surface of the work, a spring 38 is used. The spring bears at its` lower end against an adjustable threaded sleeve 39 in a lug 40 on the knife carrier. The upper end of the spring bears against adjusting nuts 41 on a stem 42 fixed to the arm 32. The downward movement of the knife carrier is limited by the engagement of the sleeve 39 with the arm 32 as shown in l `ig.` 8, so that when there is no work in the machine the knives will not engage the work support and be injured. lVhen the machine is 1n operation the verticalposition ofthe knife support is con-y trolled by a presser foot 43 fixed thereto and arranged to engage the surface of the insole just in advance of the knives. This presser foot serves to fix the depth of cut of the knives, but the depth of the cuts and their knife 26 has an inclined knives and the knife carrier are arranged as follows: The channeling knife 26 lies in an inclined slot in a block 44 which is secured to the knife carrier by a screw 45 engaging a horizontal slot 46 in the block 44. The knife is secured to the block by a plate 47 and a screw 48. By loosening the screw 45 and moving the block 44 horizontally, the distance between the cuts produced by the channeling knife and the slitting knife may be varied. The horizontal movement of the block 44 is limited by an adjustable stop screw 92 which has a collar engaging a shoulder on the recessed back of the block 44. Owing to this arrangement the block may be removed to sharpen the knife and may then be returned to exactly the same posit-ion without particular care on the part of the operator. In order to adjust the depth to which the channeling knife cuts, the knife`is moved longitudinally in the block 44 by means of a screw 49. The slitting knife is carried in an inclined slot int-he knife carrier as shown in dotted lines in Fig. 1, and is clamped therein by a screw 50 engaging the shank of the knife. By adjusting the slitting knife longitudinally the thickness of the flap cut thereby may be varied.

The hammer 51 for pressing the flaps together and setting them in their upturned position is arranged to bear against the upper side of the insole and to strike one or more blows against the inner side of the channel Hap at a point opposite the'shank of the slitting knife, so that the two flaps are' pressed and hammered together between the hammer and the slitting knife, and thereby are set in upturned position. The hammer is fixed to a carrier comprising a lever 52 pivoted at on a bell crank lever 54, which is pivoted at on an arm 56 journaled upon a stud 57 on the frame of the machine. The bell'crank lever 54 is 'restrained from movement about its pivot 55 by means comprising a spring 53, a stem 59 pivoted to the arm 56, and .adjusting nuts 60 on the steln. These means prevent movement of the bell crank lever in one direction, but permit its horizontal .arm and the pivot 53 to yield upwardly by compression of the spring 58. The lever 52 is restrained from movement about its pivot by means coniprising a spring 61 and a stem 62 sliding in the arm 56, and having adjustable stop nuts 63 to limit its movement in one direction. The stem 62 also carries adjusting nuts 64 for regulating the compression of the spring 61, and a pin 65 engaging the slotted upper end of the lever 52. By these means the lever 52 is prevented froml swinging in j scribed.

one direction about its pivot but may sion ot' the spring 61. Upon the pivot 55 is journaled a cam roll engaging a caln path 66 in the periphery ofthe cam 24, and the cam is formed to impart tro the cam roll and the parts connected therewith a plurality of oscillations during the interva s between each feeding movement so as to cause the hammer to strike the channel flap as above de- The levers 52 and 54 and the arln 56 all operate normally as one part, but the manner in which the lever 52 is mounted permits the hammer to yield horizontally according to t-he thickness of the material cut b v the knives, and the bell crank lever 54 by motion about its pivotI permits the hammer to vield inwardly according to the thickness of the insole. B'y these means the hammer is caused to press with a substantialy uniform pressure againstwork of va r ving thickness and the hammer is caused always to engage the channel Hap as low as possible` which is necessary to the best results. The hammer moves, in striking the channel tlap, substantially parallel to the upper surface of the insole and perpendicular to the lip, so that it has no tendency to beat down or collapse the channel flap as is liable to occur in previous machines in which the hammer engages the lip with a downwardly inclined movement.

The edge gage engages the edge ot the insole which is to be operated upon and regulates the distance between the edge ofthe insole and the lip formed by the knives and other inst-rumentalities. It is customary to make this distance reater at the shank portions of the insole t an around the forepart, and in order to provide for doing this or for otherwise varying the width of the margin of the insole the edge gage is made horizontally adjustablev so that its position may be varied during the operation ot the machine upon an insole. It is also arranged to move vertically so as to follow the vertical movements ot' the work support and lremain in proper relative position thereto. The edge gage 67 is mounted on a lever 68 pivoted by means of a screw 69 to a steml 70 journaled in the frame ofthe machine.` The lever 68 may swing horizont-ally about the screw 69 and the stem 70 turns freely in its journal and permits the. lever to swing vertically. The stem 70 has a threaded extremity 71 engaging a nut 72 oppositely threaded upon vits exterior and engaging a threaded socket in the vframe of the machine. By turning the nut 72 the stem 70, owing to the dii'erential action of the threads, may be moved out or in to adjust the position of the edge gage. The nut 72 is fixed in adjusted position by a: set screw 73. In order to move the edge gage during the operation of the machine to vary the width of the margin ot the insole means are provided for swinging the lever 68 about the screw 69. ',lhe outer cnd of the lever 68 is forked and engages a slide block 74 pivoted upon a plate 75 fixed to a vertical stem 76. The stem 76 is journaled in a sleeve 77 carried in a bracket 78 forming part of the trame of the machine. A plate 79 is fixed to the lower end of the stem 76 and is provided with ears 80 on Which is journaled a hand lever 81 by means of which the stem 76 and plate 75 may be turned so that by means of the block 74 the lever 68 will be swung horizontally and will move the edge gage`67 toward or from the knives. In order that this adjustment may be made quickly during the operation of the machine and without particular attention on t-he part of the operator, adjustable stops are provided for determining the positions of the hand lever 81. The plate carries an adjustable dog 82 which may be'moved about the edge of the plate 7 5 and fixed in adjusted position by a screw 83. The bracket 78 is recessed as shown in Figs. 4 and 5 so as to provide a shoulder 84 which forms a. stop aga-inst which the dog 82 bears to determine the forward position of the hand lever 81 and the position of the-edge gage in which it is nearest to the knives. In order to determine the position of the edge gage when a wider margin is desired, the hand lever 81 has xed thereto a latch 85 arranged to move in a slot in the plate 79 and to engage a notch 86 in the lower flanged end of the sleeve 77 when the hand lever is swung to the proper position. The sleeve 77 is normally fixed by a set screw 87 in the bracket 78, but the sleeve may be adjusted by loosening the screw and then swinging the sleeve by means of the latch 85 and h and lever 81. The latch 85 may be disengaged from the notch 86 by pushing the hand lever 81 down and the lever may then be swung until the. dog 82 engages the shoulderS-l, thus moving' the edge gage 67 toward the knives. The hand lever is engaged by a spring 88 tending to hold the latch in engagement with the notch 86. A spring 89 fixed to the frame of the machine bears against the front ot the inner end of the lever G8 and takes up lost motion in the mechanism for moving the edge gage. 'A spring 90 bears against the lower side of the outer end of the lever 68 and operates to keep the edge gage close to the upper surface of the work support when the latter rises and falls. The edge gage is alsovforked and has a portion engaging` the under side of the work support so as to insure their proper cooperative relation.

By means of the construction of the edge gage adjusting mechanism above described, the edge gage may be moved quickly during the operation of the machine from one fixed positlon to another, and both positions ot' the gage may be adjusted as desired.

In the operation of the machine the Work support is drawn down by means of the treadle and the Work is inserted and pressed against the edge gage by the operator. This may be done While the machine is in motion. The Vknife carrier and the feeding device operate continuously to cut and feed the work and turn up and set the flaps, and the work is guided by the operator. In passing from the shank portion to the forepart of the insole the hand lever 81 is depressed and drawn forward by the operator andwhen the shank portion on the other side of the insole is reached the hand lever is .pushed back again untilthe latch 85 engagesthe notch 86 and arrests the movement of the lever.

Although the present invention has been described as embodied in a machine for making insoles of a particular form, it is to be noted that many features of the invention are applicable to a machine for making insoles of other forms, and that the invention in its broadest aspect is not limited to the details of construction and operation illustrated and described in connection with the preferred embodiment thereof, but may be embodied in other forms broadly defined in the claims.
